Ferroptosis Metabolism Analysis Service

Ferroptosis is an iron-dependent, novel form of programmed cell death that is distinct from apoptosis, cell necrosis, and cell autophagy. Ferroptosis is characterized by an iron-dependent accumulation of lipid peroxidation to lethal levels. When cellular cysteine transport proteins are inhibited (e.g. Erastin), intracellular glutathione (GSH) is depleted, eventually leading to glutathione peroxidase (GPX4) inactivation and lipid peroxidation accumulation to a level that induces cell death. Inhibition of GPX4 enzymes (e.g. RSL3) can also lead directly to this effect. The susceptibility to iron death is closely linked to many biological processes, including amino acid, iron and polyunsaturated fatty acid metabolism, and the biosynthesis of glutathione, phospholipids, NADPH and coenzyme Q10. Ferroptosis is associated with pathological cell death associated with mammalian degenerative diseases (e.g., Alzheimer's disease, Huntington's chorea, and Parkinson's syndrome), tumors, stroke, cerebral hemorrhage, traumatic brain injury, local ischemia-reperfusion injury, and renal failure.

Based on liquid chromatography-mass spectrometry technology, Creative Proteomics can provide you with metabolite analysis in multiple biological processes such as iron ion metabolism, lipid peroxidation reactions and glutathione metabolism during the molecular regulation of iron death, accelerating the progress of your project research.
